CUT-MARKER AND STOPEMOTION FOR WARPING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 450,509, dated April 14, 1891.

Application filed April 29, 1890. Serial No. 349,898. (No model.)

To all whom, it may concern:

Be it known that 1, CHARLES DENN, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in a Out- Marker and Stop-Motion for \Varping-Machines, of which the following is a full, clear, and exact description.

My invention relates to an improved cutmarker and stop motion for warping-machines; and the object of the invention is to provide a mechanism adapted for attachment to any warper capable of automatically marking ofi any predetermined number of cuts representing a desired number of yards, and which, when the limit is reached, will automaticallyact to stop the machine,and wherein the machine will remain stopped untilset in motion again by the operator. Thus the operator is prevented from making warps of different lengths or number of cuts by neglecting to cut the warp when the marker rings the alarm.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification,

-in which similar letters and figures of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the mechanism, the portion of the frame to which it is attached being in vertical section, the said section being taken on the line 1 lof Figs. 2 and 4:. Fig. 2 is a section on the line 2 2 of Figs. 1 and 4, looking in the direction of the arrows. Fig. 3 is an enlarged plan view of one portion of the mechanism. Fig. 4 is a similar view of another portion of the mechanism,

. and Fig. 5 is a partial side elevation of the rack-bar.

' To the frame 10 of a warping-machine of any desired description, preferably parallel with and at one side of the drive-shaft 11, ahorizontal girder 12 is attached, and beneath the drive-shaft an extension 13 of the main frame is formed, which projects beyond the opposite side of the shaft, as best shown in Fig. 2.

Upon the face of the girder contiguous to the drive-shaft, at any desiredpoint between the ends of the said girder, a plate 14 is rigidly secured, which plate is provided with integral or attached mortised lugs 15, 16, and 17 upon its face, the lug 15 being located at one lower corner. The lug 16 is preferably of sufficient length to extend from top to bottom of the plate at the other end thereof, the mortised lug 17 being preferably located near the central portion of the upper edge of the plate, as is best illustrated in Fig. 1. In the lower portion of the lug 16 and in the opposed lug 15 a rack-bar 18 is held to slide, the said bar having its teeth produced upon the upper edge, and in the said bar, preferablybetween the center and one end, aseries of apertures 19 is produced, over each of which apertures a numeral is placed, the said numerals representing marks, and the numbers may run from 1 as high as maybe desired, as is best shown in Fig. 5.

Upon the plate, near the end having the lug 15 attached, a spring-pressed pawl 20 is pivoted, which pawl is held constantly in engagement with the teeth of the rack-bar and prevents the said bar from sliding backward, as to the rear end of the bar a rope or chain 21 is secured, which rope or chain passes over a suitable friction-pulley attached to the girder and has a weight 22 secured to its lower end.

In the uppermortised portion of the lug 16 and in the mortised lug 17 a cam-bar 23 is held to slide parallel with the rack-bar. The cam-bar extends some distance beyond the outer edge of the mortised lug 16 and islimited in its rearward movement by a screw 24., secured thereto and adapted for engagement with the inner edge of the said lug, and this screw is normally held in contact with the lug and the bar returned to its normal position (illustrated in Fig. 1) by a spring 25, attached at one end to the lug and at its other end to the bar.

Upon the inner end of the cam-bar 23 a dog 26 is pivoted, which dog contacts with the teeth of the rack-bar, and when the cam-bar is moved forward is adapted to propel the rack-bar in the same direction. The forward IOO or extreme outer end of the drive-shaft is provided with a fast pulley 27 and a loose pulley 28, and near the extension 13 of the main frame the said drive-shaftis provided with an attached cam 29. At a point about centrally between the ends of the plate 14 a Worm is formed upon the said drive-shaft, as best shown in Figs. 1 and 3.

In a suitable bearing 31, located upon the top of the girder, a transverse shaft 32 is journaled, and upon one end of said shaft a worm-wheel 33 is secured, which meshes with the Worm 30 of the drive-shaft. Upon the opposite end of the shaft a pinion 34 is secured, which pinion conveys movement to a changewheel 35, secured to a shaft 36, also journaled upon the girder at the rear of its parallel shaft 32, as is best shown in Fig. 3, through the medium of an intermediate gear 37, which gear is journaled on a stud upon one side of the girder and meshes with the change-wheel 35 and pinion 31-. The shaft 36 extends through and beyond both sides of the girder, and upon the inner end of the shaft a paint-can or receptacle 38 is rigidly attached, which receptacle is preferably of disklike or circular contour, and is provided at one point upon its periphery with a vertical spout 39, in which spout a wick 40 is placed, the

lower end of the wick being in contact with the contents of the can, while the upper end of the wick is made to project slightly beyond the outer surface of the spout, and upon the shaft 36, between the paint-can and the inner side face of the girder, a cam-collar 41 is secured, provided with a projecting peripheral pin 42, which pin is preferably rounded off at one outer corner, and as the shaft 36 revolves and the change-wheel has made one revolution the rounded surface of the pin 42 is brought in contact with the rear end of the cam-bar 23, and the said bar is pushed forward thereby, thus moving the rack-bar one tooth in the same direction.

Upon the girder 12, above the forward end of the rack-bar 18, a gong 43 of any desired construction is located, and upon one side of l the said forward end of the rack-bar an upwardly-extending pin 44 is secured, which pin is adapted for contact with a lever 45, attached to the hammer of the gong. The ob ject of the pin is to elevate the lever 45 and retract the hammer when it contacts with said lever from the rear, and when the rack-bar has been propelled a proper distance forward the pin passes the lever, releasing the same and causing the hammer to contact with the gong and sound an alarm.

An angled bar 46, the upper end of which is inclined downward, is attached to the forward extremity of the rack-bar in any suitable or approved manner, and the extremity of the inclined member of the angled bar 46 is adapted to slide in a slot 47 produced in the upper end of a vertically-movable liftbar 48. The upper wall of the slot 47 of the lift-bar is beveled, as best shown in dotted L lever is constantly vibrated.

lines in Fig. 1, and the said bar is held to slide in suitable guide-sockets 49, attached to the inner face of the girder at a point almost opposite the cam 29 of the drive-shaft. The lift-bar is limited in its downward movement by a pin 50, secured in one side and adapted for contact with the upper surface of the lower guide-socket, as best shown in Fig. 2, and to the lower end of the bar apendent angled or L-shaped bracket 51 is secured, the horizontal member whereof is at the lower end and extends outward into the extension 13 of the frame.

In the extension 13 of the frame a lock-lever 52 is fulcrumed at ornear its center, and to the lower end of the leverone end of a finger 54 is pivoted,which finger, when the machine is in operation, hangs downward at an obtuse angle to the lever and is supported by and rests upon the horizontal member of the bracket 51 of the lift-bar, and in front of the bracket 51 of the lift-bar a vertical lever 55 is centrally fulcrumed to the inner portion of the extension of the main frame, as illustrated in Fig. 2, the lower end of which lever is essentially in horizontal alignment with the lower end of the opposite lever 52, and the upper end of the lever 55 is adapted for contact with the cam 29 of the drive-shaft 11. Thus when the said shaft is in operation the The two levers 52 and 55 are normally retained in proper relation with each other by means of a spring 56 secured thereto.

In suitable bearings 57, attached, preferably; to the outer side of the extension 13 of the frame, a horizontal shifting rod 58is held to slide. The rod 58 is cylindrical for the greater portion of its length; but one end thereof is flattened as illustrated at 59 in Fig. 4, and the flattened end extends'beyond the extension of the frame, and is provided at its extremity with a shifting fork 60, the tines of which fork engage with the sides of the driving-belt 61, and upon the inner face of the flattened portion 59 of the shifting rod a preferably wedge-shaped stop 62 is secured, adapted to engage with one side of the locking-lever 52 when the driving-belt 61 is upon the driving-pulley of the main shaft. This locking-lever retains the fork in such position that it will hold the belt upon the drive-pulley against the tension of the spring 63, which is coiled around the cylindrical portion of the shifting rod, contacting at one end with the bearing 57 of the said rod and at its other end with a collar 64, attached to the rod, as illustrated in Figs. 4 and 6. The very moment that the lock-lever is carried out of contact with the shifting rod the spring 63 acts to force forward the fork 60, carrying the belt 61 upon the idle pulley of the driveshaft, and stop the movement of the machine.

The wheel 35 is called a change-wheel, be-

cause the size of the circumference of the wheel regulates the number of yards in a cutas, for instance, the wheel may be ofa diameter yards in a cut.

sufficient to permit ten yards of Warp to pass by during one revolution,the cutbeingmade at each revolution of the wheel. The direction of the travel of the warp is transversely beneath that portion of the girder at which ,the paint-can is located, as illustrated at the dotted line A in Fig. 3.

In operation, if it is determined, for instance, that the length of the warp shall be twenty cuts a pin B (illustrated in Fig. 1) is placed in the aperture of the rack over which the numeral 20islocated,and before starting the machine the rack is carried back, assisted by the weight 22, until the said pin is brought in contact with the rear mortised lug 16 of the plate 14. The machine having been set in operation, at each revolution of the changewheel the wick of the paint-can will mark the warp, and as the warp is marked the pin 42 upon the same shaft with the paint-can forces the cam-bar 23 forward, which bar may be properly called a push-bar, whereupon the dog 26 of the bar, acting directly upon the teeth of the rack 18, carries the rack forward one tooth, in which position it is held by the pawl 20, and when the rack-bar has been propelled forward twenty teeth the pin 44 at the forward end of the rack will have passed the lever 45 of the gong and caused an alarm. At the same moment the angled extension of the rack enters the slot 47 of the lift-bar 48 a sufficient distance to draw said bar upward, whereupon the finger 54, attached to the locklever 52, is elevated to the horizontal position shown in Fig. 2, and as the lever 55 is rocked forward at its lower end by contact with the cam 29 of the drive-shaft the said vibratory lever 55 forces the finger 54 outward, whereupon the upper end of the locklever is carried inward to the position shown in dotted lines, Fig. 2, and the shifting bar 58 is released from the lever, and the spring 63 upon said bar immediately acts and carries the belt over the loose pulley of the machine, and said machine is immediately stopped. The operator, should he be delayed, can come at leisure and cut the warp and carry back the rack-bar 18, so that the pin B therein will again engage wit-h the mortised' lug 16, and the shifting rod is pulled inward, preferably by means of an attached rope 0, (shown in Fig. 3,) until the belt is carried to the driving-pulley, and when so carried the stop 62 thereon will engage with the lock-lever, which is again in its normal position, and the belt is thereby held to place.

It will be readily understood from the foregoing that a screw or pin inserted in any one of the apertures in the rack determines or defines the number of cuts in the warp and that the change-wheel defines the number of Therefore for convenience I denominate the rack a cut-defining rack.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a machine of the character described,
